Source Control (Respiratory Disease)

Source control in the context of respiratory diseases refers to the measures taken to prevent the spread of pathogens from an infected individual to others in the surrounding environment. This is particularly important in the management of airborne diseases, which are primarily transmitted through respiratory droplets.

Overview

Source control strategies are a critical component of infection control in healthcare settings, especially during outbreaks of respiratory diseases such as COVID-19, influenza, and tuberculosis. These strategies aim to reduce the risk of transmission from symptomatic individuals (the "source") to others, particularly healthcare workers and other patients.

Strategies

Respiratory Hygiene

Respiratory hygiene or cough etiquette is a simple yet effective source control measure. It involves covering the mouth and nose with a tissue or the elbow during a cough or sneeze, and proper disposal of tissues.

Use of Personal Protective Equipment

The use of Personal Protective Equipment (PPE) such as masks and respirators can serve as a physical barrier to prevent the spread of pathogens. The Centers for Disease Control and Prevention (CDC) recommends the use of masks for source control, particularly in healthcare settings.

Isolation

Isolation of infected individuals is another key source control strategy. This can be achieved through the use of isolation rooms or areas, particularly for patients with known or suspected airborne diseases.
